DOUGLAS BEARDSLEY AND FRANK A. ROBINSON, OF AUBURN, NEW YORK; SAID ROBINSON ASSIGNOR TO SAID BEARDSLEY.

SAILING-VESS EL.

SPECIFICATION forming part of Letters Patent No. 537,667, dated April 16, 1895.

Application filed December 5, 1894- Serial No. 530,878. (No model.)

To aZZ whom, it may concern:

Be it known that we, DOUGLAS BEARDSLEY and FRANK A. ROBINSON, of the city of Au burn, New York, have invented certain new 5 and useful Improvements in Sailing-Vessels,

of which the following is a description, reference being bad to the accompanying drawings, forming part of this specification.

The object of our invention is to cause the I0 pressure upon the sails to be resisted by the weight of the ballast, without rocking the hull of the vessel.

It further consists in providing the hull with a fin or center board, for lateral resistance, which remains in a vertical position,

owing to the freedom of the hull from rocking, while the spars and sails may be-inclined sidewise by the wind pressure, such inclination being resisted by means of a ballasted 2o lever arm which is pivoted to the hull and secured in the same vertical plane as the sails. In the drawings, Figure l, is a side view of a sailing vessel, showing the side broken out to permit our invention to be seen. Fig. 2, is a side view of our improvement upon a larger scale. Fig. 3 shows a front, side, and plan view, of the mast, spreader, and step. Fig. 4, shows side and end views of the shaft, made double at its central part to permit a center 0 board to be dropped between its two arms. Fig. 5, is a side view of the center board construction, having the central part of the shaft removed, and the rearward ballast supporting arm hinged at the keel. Fig. 6, is a front view 5 of the same.

Similar reference-letters indicate like parts in the several figures.

In the drawings, A is the mast; B, asocket or step for the mast, which is secured upon a The shrouds are secured below to the ends of a spreader, D, which is placed at the upper end of the socket, B. The shaft, C, is inclined upward, so that its axis of revolution produced would pass through the point where the jibstay meets the bowsprit. The object of this arrangement is to permit the mast to swing laterally without changing the length of the jibstay. The rear end of the shaft, 0, is coupled to the front end of the shaft, E, which is supported in bearings, e, c, Fig. 2, and preferably placed horizontally, or as nearly so as is possible. The keel is cut away and provided with a box, F, opening downward. It will thus be seen that wind pressure upon the sails may cause the mast to yield and move to leeward, by revolving the shaft, 0, in its bearings. This transmits its motion through the shaft section, E, to the arms, G, G, and thence to the ballast, H, without rocking the hull.

The hull is provided with lateral resistance by means of a pin, K, bolted beneath the keel, or else by means of a center board, as shown in Fig. 5. The board, L, is pivoted at, Z, in the usual manner, and works within the trunk, m.

In the use of the center board, it becomes necessary to provide for its vertical motion, either by making the shaft, E, double, as shown in Fig. 4, at its central part, or else by dispensing with this portion of the shaft altogether, as shown in Fig. 5, by operating the ballast from the front arm, and simply hinging the rear arm to the keel, as shown, at, n. The use of either the fin, K, or the center board, L, in fixed position with respect to the hull, that is in the vertical longitudinal central plane of the hull, accomplishes the same purpose, of retaining the lateral resistance of So the hull in vertical position, while the mast and sails may yield and be pushed to leeward, and the ballast be brought into play to counterbalance this pressure. Consequently in .the claims we designate the devices which ex- I tend beneath the hull for the purpose of creating a lateral resistance, a lateral resistance plate, and we intend thereby to indicate a genus which may include as species both fixed fins and movable center boards as well as other equivalent devices performing the same function.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is- 5 1. The hull of a sailing vessel provided with a lateral resistance plate extending below the keel, in combination with the mast, A, pivotally secured to said hull, and the ballast, H, also pivotally secured to said hull, said mast 1 and ballast being secured together by the shafts, O, and E, so as to remain in the same longitudinal plane, while they may vibrate laterally with respect to said hull.

5 2. The hullofasailingvessel,providedwith a lateral resistance plate extending below the keel, in combination with a mast, pivoted to said hull by means of the inclined shaft, C, and the ballast, I-I, supported by arms, G, G,

, secured upon the shaft, E, which is journaled to in horizontal position within said hull, and is connected to the shaft, 0, so as to revolve therewith.
